DESCRIPTION OF EXECUTION FORMS

[0009] A hydraulic excavator, as an example of a working machine according to the present disclosure, is described below with reference to the drawings. ConfigurationOutline Hydraulic Excavator 1

[0010] Fig. Figure 1 is a schematic view illustrating the configuration of a hydraulic excavator 1 of the present embodiment.

[0011] As in Fig. As illustrated in Figure 1, the hydraulic excavator 1 (an example of a working machine) includes a drive body 2 and a rotating body 3.

[0012] The chassis 2 includes a pair of drive units 2a and 2b. The drive units 2a and 2b include crawler tracks 2c and 2d, respectively. The driving force of an internal combustion engine sets a drive motor in rotation, and the crawler tracks 2c and 2d are driven to move the hydraulic excavator 1.

[0013] The rotating body 3 is positioned above the transport body 2. The rotating body 3 is configured to be rotated about an axis in an up-down direction relative to the transport body 2 by a rotary motor (not illustrated). A pivoting mechanism is arranged within the rotating body 3. A pivoting circle is arranged within the transport body 2 and engages with the output pinion of the pivoting mechanism. The rotary drive of the rotating motor is braked by the pivoting mechanism (not illustrated) and output by the pinion. As a result, the pivoting mechanism rotates either inside or outside the pivoting circle, causing the rotating body 3 to rotate relative to the transport body 2.

[0014] The rotating body 3 encloses a rotating frame 11, a cabin 12, a working device 13, an engine compartment 14, a walkway 15, handrails 16a and 16b, a storage box 17 and the reducing agent tank 18 (in Fig. 8(a) below).

[0015] The rotating frame 11 is arranged above the chassis 2 and is a frame that can rotate relative to the chassis 2. The cabin 12 is located at the front left position of the rotating frame 11. The cabin 12 is equipped with an operator's seat in which an operator sits during operation. Inside the cabin 12 are an operator's seat, a control device for operating the work tool 13, a display device, or the like.

[0016] In the present embodiment, the directions front, rear, left, and right of the hydraulic excavator 1 are described with reference to the operator's seat in the cab 12. The direction in which the operator's seat faces forward is referred to as the forward direction Xf, and the direction opposite to the forward direction is referred to as the reverse direction Xb. The right and left directions when the operator's seat faces forward are referred to as a right direction Yr and a left direction Yl, respectively.

[0017] The working device 13 is attached to the front center position of the rotating frame 11. The working device 13 includes a boom 21, an arm 22, and an excavator bucket 23, as shown in Fig. Figure 1 illustrates this.

[0021] The first tread 31a, the second tread 31b, and the third tread 31c are arranged horizontally. The first tread 31a, the second tread 31b, and the third tread 31c are arranged in this order, starting from the bottom. The first tread 31a, the second tread 31b, and the third tread 31c are arranged in this order, from front to back. A step is provided between the first tread 31a and the second tread 31b. The first stepped surface 31d is arranged between the rearward-facing side edge Xb of the first tread 31a and the forward-facing side edge Xf of the second tread 31b. The first stepped surface 31d is arranged perpendicular to the forward-backward direction. A step is provided between the second tread 31b and the third tread 31c.The second stepped surface 31e is arranged between the side edge of the second step surface 31b pointing in the backward direction Xb and the side edge of the third step surface 31c pointing in the forward direction Xf. The second stepped surface 31e is arranged perpendicular to the forward-backward direction.

[0022] The second catwalk section 32 is arranged from the rear end of the first catwalk section 31 towards the left in the direction of Yl. The second catwalk section 32 extends to the rear of cabin 12, as shown in Fig. Figure 1 illustrates the second catwalk section 32, which is located at the front of the ceiling of the engine compartment 14.

[0023] The first step surface 31a of the first walkway section 31 forms the floor surface of a work area S. The work area S is provided on the first step surface 31a.

[0024] Handrails 16a and 16b are arranged at the end of the first walkway section 31 of the walkway 15. Handrail 16a is located on the front of the first tread surface 31a of the first walkway section 31. Handrail 16b is located on the right side surface of the first walkway section 31, running along its length. The access point 15a of the walkway 15 is formed between the right surface end of handrail 16a and the front end of handrail 16b. Storage box 17

[0025] The storage box 17 includes a lid 40 which can be opened and closed to store tools or the like used for maintenance. Fig. 2B is a view illustrating a state in which the lid 40 of the storage box 17 is removed. Fig. 2A is open. As in Fig. As illustrated in Figure 2B, a tool bag 91 and a bucket 92 or the like are stored in the storage box 17.

[0026] Fig. 2C is a perspective view of the area around storage box 17. Fig. In 2C, handrails 16a and 16b are omitted. The storage box 17 is located to the left of the work area S. Fig. 3A is a perspective view of the area around storage box 17 as seen from the rear direction Xb. In Fig. 3A omits the second step surface 31b and the reducing agent tank 18.

[0027] The storage box 17 is arranged adjacent to the first step 31a. The storage box 17 is located opposite the access 15a to the walkway 15 on the other side of the first step 31a. The storage box 17 encloses a first side surface 41, a second side surface 42, a third side surface 43, a fourth side surface 44, an upper surface 45, an inclined surface 46, and a lower surface 47. Fig. 4A) and a shelf 48, as in Fig. 2C and Fig. 3A illustrates this.

[0028] The first side surface 41 faces the work area S (first step surface 31a), as shown in Fig. Figure 2C illustrates this. The first side surface 41 is arranged perpendicular to the left-right direction. The second side surface 42 is arranged such that it is opposite the first side surface 41. The second side surface 42 is arranged perpendicular to the left-right direction. The second side surface 42 is located on the left side of the first side surface 41. In this patent specification, the term "perpendicular" or "vertical" need not mean perpendicular or vertical in the strict sense; it may include errors and may be understood as perpendicular or vertical within the framework of usual social conventions. In this patent specification, the term "horizontal" need not mean horizontal in the strict sense; it may include errors and may be understood as horizontal within the framework of usual social conventions.

[0029] As in Fig. As shown in Figure 2C, the third side surface 43 is arranged such that it connects the front end of the first side surface 41 and the front end of the second side surface 42. The third side surface 43 is arranged perpendicular to the forward-backward direction. As shown in Fig. As illustrated in Figure 3A, the fourth face is arranged such that it connects the rear end of the first face 41 and the rear end of the second face 42. The fourth face 44 is arranged perpendicular to the forward-backward direction. The fourth face 44 is arranged so that it is opposite the third face 43.

[0030] The upper surface 45 is arranged such that it connects the upper end of the second side surface 42, the upper end of the third side surface 43 and the upper end of the fourth side surface 44, as shown in Fig. Figure 2C illustrates this. The upper surface 45 is arranged perpendicular to the upward-downward direction. The inclined surface 46 is arranged between the first side surface 41 and the upper surface 45. The inclined surface 46 is positioned such that it connects the right end of the first side surface 41 and the upper end of the first side surface 41. The inclined surface 46 is inclined so that it runs downwards towards the working area S (first step surface 31a).

[0031] As in Fig. 2C and Fig. As illustrated in Figure 3A, the cover 40 extends over the first side surface 41, the inclined surface 46, and the upper surface 45. As shown in Fig. As illustrated in Figure 3A, the left end of the cover 40 (opposite the working area S) is rotatably connected to the upper end of the second side surface 42 by a hinge 49. Two hinges 49 are arranged side by side in a forward-backward direction.

[0032] A rod-shaped element 50 is attached to the lid 40 to maintain an open state. Fig. 3B is an enlarged view of section B of Fig. 3A. The rod-shaped element 50 is arranged between the cover 40 and an inner surface 51. The rod-shaped element 50 is arranged at an angle with respect to the upward-downward direction. The rod-shaped element 50 is arranged so that it is inclined upwards in the left direction Yl. The rod-shaped element 50 is arranged between the cover 40 and the inner surface 51. The inner surface 51 is arranged near the inner side (rear side) of the third side surface 43. The inner surface 51 is arranged so that it is opposite the third side surface 43. A first end section 50a of the rod-shaped element 50 is bent backwards and rotatably attached to a bracket 52, which is attached to an inner surface 40a of the cover 40. A second end section 50b of the rod-shaped element 50 is bent forwards and inserted into a through-hole 53 formed in the inner surface 51.

[0033] The through-hole 53 has a first end 53a and a second end 53b. The through-hole 53 extends horizontally from the first end 53a to the right and then downwards to the right until it reaches the second end 53b. The first end 53a is concave downwards. As shown in Fig. As illustrated in Figure 3B, when the lid 40 is open, the second end section 50b is positioned at the first end 53a of the through-hole 53 and fits into the concave shape of the first end 53a. Even when the operator removes their hand from the lid 40, the second end section 50b does not move through the through-hole 53 and the lid 40 can be held open.

[0034] When the cover 40 is closed, the second end section 50b of the rod-shaped element 50 can be released from the assembled state of the first end 53a in the concave shape by slightly lifting the cover 40. In this state, the second end section 50b can move along the through-hole 53 towards the second end 53b, allowing the cover 40 to be closed.

[0035] Fig. 4A is a view showing the internal configuration of storage box 17 from the perspective of an arrow A in Fig. 3A shows. In Fig. In 4A, the third side surface 43 and the inner surface 51 are omitted. Fig. 4A shows the lid 40 in an open state, illustrated by a two-dotted dashed line. Fig. 4A shows the hatched work area S. The work area S is a space above the first step surface 31a, which is a floor area. As in Fig. As illustrated in Figure 4A, the lower surface 47 of the storage box 17 is located below the first step surface 31a. Thus, part of the storage box 17 is recessed into the rotating frame 11. This allows the length of the storage box 71 to be increased in the upward-downward direction, making it possible to store a long object in the storage box 17 in this direction.

[0036] The insert 48 is arranged inside the storage box 17 and is movable, as shown in Fig. 4A illustrates this. Fig. 3A and Fig. As illustrated in Figure 4A, the tool bag 91 is placed on the shelf 48. The bucket 92 is placed under the shelf 48. The bucket 92 is placed on the lower surface 47, as shown in Figure 4A. Fig. 4A illustrates this. Fig. 4A illustrates the insert 48 in a horizontal state as a solid line and the insert 48 in a vertical, upward-swiveled state as a two-dot dashed line.

[0037] Fig. 4B is an enlarged view of section C of Fig. 4A. As in Fig. As illustrated in Figure 4B, a support projection 54 extends to the right Yr within the second side surface 42. Although not shown, the support projection 54 is provided at each of two locations in the forward-backward direction. The shelf 48 is connected to the support projection 54 via a hinge 55. The hinge 55 is attached to the underside of the left Yl side edge of the shelf 48. Thus, the shelf 48 is configured such that the right Yr side edge can pivot in an upward-downward direction, with the left Yl side edge forming the midpoint. In the pivoted position, the shelf 48 is arranged vertically along the second side surface 42.

[0038] The 48 mm shelf is configured so that both the horizontal and the upward-swinged vertical positions can be maintained. As shown in Fig. 3B and Fig. As illustrated in Figure 4B, the insert 48 encloses a main body 61 and a projecting element 62. The main body 61 has a box shape, on which, for example, the tool bag 91 is placed. The projecting element 62 extends forward from the main body 61 in the direction Xf. The projecting element 62 has a cylindrical shape.

[0039] A lower clamping element 63 is arranged on the inner surface 51 via a bracket 64. As in Fig. As illustrated in Figure 3B, the bracket 64 is arranged on the inner surface 51. The lower clamping element 63 is attached to the bracket 64. The lower clamping element 63 is an elastic element. As shown in Fig. As illustrated in Figure 4B, the lower clamping element 63 has an upwardly directed opening 63a.

[0040] When the shelf 48 is pivoted downwards to become horizontal, the protruding element 62 is also pivoted downwards when the main body 61 is pivoted downwards and is inserted into the lower clamping element 63 from the opening 63a and clamped in place. The lower clamping element 63 elastically holds the protruding element 62 within it. This allows the shelf 48 to be held horizontally.

[0041] An upper clamping element 65 is attached to the inner surface of the third side surface 43. The upper clamping element 65 has the same shape as the lower clamping element 63. The upper clamping element 65 has an opening 65a in the right direction Yr.

[0042] When the shelf 48 is pivoted upwards to become vertical, the projecting element 62 is also pivoted upwards when the main body 61 is pivoted upwards and is inserted into the upper clamping element 65 from the opening 65a and clamped in place. The upper clamping element 65 elastically holds the inserted projecting element 62 securely. Thus, the shelf 48 can be held vertically.

[0043] The following describes how to remove the tool bag 91 and the bucket 92 from the storage box 17. Fig. Figures 5(a) to (e) are views illustrating the removal of the tool bag 91 and the bucket 92.

[0044] As in Fig. As illustrated in Figure 5(a), the lid 40 of the storage box 17 is open. The second end section 50b of the rod-shaped element 50 is fitted into the concave shape of the first end 53a of the through-hole 53 and the lid 40 is held open.

[0045] Next, as in Fig. Figure 5(b) illustrates the removal of the tool bag 91 from the storage box 17, which was placed on the shelf 48. The horizontal state of the shelf 48 is maintained, with the protruding element 62 inserted into the lower clamping element 63.

[0046] Next, the protruding element 62 of the insert 48 is removed from the inside of the lower clamping element 63 and the insert 48 is pivoted upwards (see Fig. 5(c)). Fig. 6 is a view illustrating a state in which the shelf 48 of Fig. 4A has been swung upwards. As in Fig. As illustrated in Figure 6, by inserting the protruding element 62 into the upper clamping element 65 through the opening 65a, the protruding element 62 is held by the upper clamping element 65 and the insert 48 is held in an upwardly pivoted state.

[0047] Next, as in Fig. Figure 5(d) illustrates the removal of bucket 92. The removed bucket 92 can be placed on the first step 31a, as shown in Fig. Figure 5(e) illustrates this. Since the lid 40 is formed over the upper surface 45, the inclined surface 46 and the first side surface 41, the opening is large when the lid 40 is open, and thus the bucket 92 can be easily removed, as shown in Figure 5(e). Fig. 5(d) illustrates.

[0048] As in Fig. As illustrated in Figure 7(a), an operator H can place the bucket 92, removed from the storage box 17, on the first step 31a of the work area S. In the present embodiment, the area of ​​the first step 31a can be enlarged so that the bucket 92 can be placed next to an operator P on the first step 31a, which is the lower surface of the work area S. Fig. 7(a) the tool bag 91 is placed on the second step 31b, but can also be positioned as in Fig. 7(b) illustrates that it can be placed on the second step 31b. Reducing agent tank 18

[0049] The reducing agent tank 18 is located below the second step 31b. The reducing agent tank 18 is located adjacent to the first step 31a. As shown in Fig. As illustrated in Figure 2C, a cover 70 is arranged over the reducing agent tank 18. The cover 70 extends over the second stepping surface 31b and the first stepped surface 31d. As shown in Fig. As illustrated in Figure 2C, the front of the lid 70 is pivoted in an upward-downward direction around the edge pointing towards the reverse direction Xb. Fig. 8(a) is a perspective view illustrating a state in which the lid 70 is open.

[0050] Fig. Figure 8(a) is a perspective view from above illustrating a state in which the operator is refilling the reducing agent into the reducing agent tank 18. As shown in Fig. As illustrated in Figure 8(a), a refill opening 18a of the reducing agent tank 18 faces the work area S (first step 31a). The operator H holds a refill tank 93 and refills the reducing agent from the work area S into the refill opening 18a. At this point, as shown in Figure 8(a), the refill opening 18a is located at the work area S. Fig. Figure 8(b) illustrates that, viewed from the forward direction Xf, the inclined surface 46 is provided between the first side surface 41 and the upper surface 45 of the storage box 17, thus preventing the operator's knee H1 from hitting the storage box 17 and facilitating refilling. Features

[0051] (1) The hydraulic excavator 1 according to the present embodiment includes the chassis 2 and the rotating body 3. The rotating body 3 includes the slewing frame 11, the first tread 31a, and the storage box 17. The slewing frame 11 is rotatably mounted above the chassis 2. The first tread 31a is mounted on the slewing frame 11. The storage box 17 is located adjacent to the first tread 31a. The storage box 17 includes a movable insert 48.

[0052] By arranging the movable shelf 48 in the storage box 17 in this way, storage items can be arranged in an upward-downward direction, and the surface area of ​​the storage box 17 can be reduced. Thus, the first step surface 31a can be positioned far to the side of the storage box 17, and as shown in Fig. 8(a) and Fig. As illustrated in Figure 8(b), the space for placing storage items (e.g. tool bag 91 or bucket 92) can be provided on the first step 31a.

[0053] (2) In the hydraulic excavator 1 according to the present embodiment, the storage box 17 encloses the upper surface 45 and an inclined surface 46, which is arranged on the side of the upper surface 45 facing the first footplate 31a. The inclined surface 46 is inclined downwards towards the first footplate 31a.

[0054] By providing the inclined surface 46 in the storage box 17 in this way, the corner on the side facing the first step surface 31a is not provided, and the operator's knee H1 does not abut the storage box 17, as shown in Fig. Figure 8(b) illustrates how this facilitates the refilling of the reducing agent.

[0055] (3) In the hydraulic excavator 1 according to the present embodiment, the storage box 17 further encloses the first side surface 41. The first side surface 41 faces the first footplate 31a. The inclined surface 46 is arranged between the first side surface 41 and the upper surface 45. The storage box 17 encloses the opening lid 40, which extends over the first side surface 4, the inclined surface 46 and the upper surface 45.

[0056] In this way, the lid 40 is formed over the upper surface 45, the inclined surface 46 and the first side surface 41, so that the opening is large when the lid 40 is open and therefore the bucket 92 can be easily removed, as shown in Fig. 5(d) illustrates.

[0057] (4) In the hydraulic excavator 1 according to the present embodiment, the storage box 17 encloses the first side surface 41 and the second side surface 42. The first side surface 41 faces the first footplate 31a. The second side surface 42 is opposite the first side surface 41 and is located on a side opposite the first footplate 31a with respect to the first side surface 41. The insert 48 is pivotably attached to the second side surface 42 via the hinge 49. This allows the insert 48 to be pivoted from a horizontal position, in which an object can be placed, to a vertical position, in which an object can be removed from under the insert 48.

[0058] (5) In the hydraulic excavator 1 according to the present embodiment, the storage box 17 encloses the floor area 47 which is located below the first footplate 31a of the working area S.

[0059] Thus, part of the storage box 17 can be recessed into the rotating frame 11, increasing the length of the storage box 17 in the upward-downward direction, allowing a long object such as the bucket 92 to be stored in the storage box 17 in an upward-downward direction.

[0060] (6) The hydraulic excavator 1 according to the present embodiment further includes the walkway 15 including the first tread surface 31a, which is configured to serve as a step. The storage box 17 is arranged adjacent to the walkway 15.

[0061] Since the storage box is not installed on the catwalk 15 in this way, the operator can pass the catwalk 15 even when the lid 40 of the storage box 17 is open.

[0062] (7) In the hydraulic excavator 1 according to the present embodiment, the access 15a to the first step 31a is located on the right side face 3a of the rotating body 3. The storage box 17 is located opposite the access 15a on the other side of the first step 31a. The walkway 15 extends from the first step 31a to the rear of the rotating body 3.

[0063] Thus, even with the lid 40 of the storage box 17 open, the operator can move across the walkway 15 to the rear of the rotating body 3.

[0064] (8) The hydraulic excavator 1 according to the present embodiment encloses the reducing agent tank 18 and the cover 70.
